Assembly & Installation Instructions
Assembly and installation of the submersible battery pack must be performed in a clean
environment to ensure proper seal of waterproof enclosure, and on a large flat surface, free of
contaminants or obstructions.
Step 1:Label Batteries
Label the batteries from 1-4 with a permanent marker to ensure proper installation of each
independent cell within the enclosure. Place the four battery pack cells in a 2 by 2
configuration, with cell 1 and 2 on top (orientated from left to right; positive (red) -negative
(black) and positive (red) - negative (black)) and 3 and 4 on the bottom (orientated from left to
right; negative (black) - positive (red), and negative (black) -positive (red)). Obtain proper
battery sequence prior to moving to step 2.

Step 2: Install Battery Cells into the
Submersible Battery Box
For easy installation of battery cells into battery box,
tilt battery box vertically so opening is orientated
upward and label on outside of box is facing away
from you. Install battery cell #4 into bottom right
position of battery box (orientation is negative-
positive). Install battery cell #3 into bottom left
position of battery box (orientation is negative-
positive). Install Battery cell #2 into top right position
of battery box (orientation is positive-negative). Install
Battery cell #1 into top left position of battery box
(orientation is positive-negative).
TIP: Battery box is constructed for tight fit of each cell
within box, allowing batteries to drop into place is
acceptable. If you have trouble achieving proper
battery placement, please contact us.
Step 3:Battery Management System
Observe the battery management system (BMS) located at the center of the battery pack entry
plate. This device maximizes the charging sequence for each 3.2 V cell within the submersible
battery pack. Each positive terminal of all (4) battery cells will connect to the BMS via labeled
(Red) wire. In addition, the negative (blue/black) wire will connect the BMS to the negative
terminal of battery #4.

Step 4: Install Bus Bars & BMS Wiring for 12 Volt Battery
Configuration
Lay the battery box (Horizontally) onto a
flat surface with the battery label faced up.
Remove vertical (Left) bus bar and
associated battery terminal hardware from
included packaging. Slide ring terminal of
Red wire (labeled #1 extending from BMS)
over end of provided battery terminal bolt,
and through top hole of vertical bus bar.
NOTE: Proper placement of hardware is in
the following order - Bolt- head-split lock
washer-flat washer-ring terminal-bus bar.
Install bolt/ring terminal/bus bar assembly into positive terminal of battery cell #1, and hand
tighten. Install remaining terminal bolt into bottom hole of vertical bus bar and into negative
terminal of battery #3.
Next, remove from packaging and install horizontal bus bar from negative terminal of battery #1
to positive terminal of battery #2 (repeat above process to ensure (Red) #2 wire from BMS is
installed to positive terminal of battery #2).
Install remaining vertical bus bar from negative terminal of battery #2 to positive terminal of
battery #4 (repeat above process to ensure (Red) #4 wire from BMS is installed to positive
terminal of battery #4).

Step 5. Connect Entry Plate to Battery Cells
Place the battery entry plate in front of the battery box assembly with the positive (Red) wire
facing left, and negative (Black) facing right.
Install positive (Red) wire extending from the battery pack entry plate to positive terminal of
battery #3. Ensure positive (Red) wire extending from battery pack entry plate, and (Red)
wire labeled #3 from BMS, are placed onto terminal bolt and secured to positive terminal
of battery #3.
Repeat similar steps to install negative (Black) wire extending from battery pack entry plate, and
(Black) #4 black wire extending from BMS, to negative terminal of battery #4.
Step 6. Properly Tighten Battery
Terminal Hardware
Unpackage provided torque screwdriver and
set to 30-inch pounds.
*NOTE: Failure to torque battery hardware to
manufacturer’s specifications may cause
adverse battery performance.
